terraform-bootstrap

This repository can be used as a template for repositories carrying Terraform code.

The repository holds the following configuration files, which help develop terraform code:

• .editorconfig -> EditorConfig helps maintain consistent coding styles for multiple developers working on the same project across various editors and IDEs. More about project under https://editorconfig.org/
• .pre-commit-config.yaml -> framework for managing and maintaining pre-commit git hooks. More about project under https://pre-commit.com/. In this config following hooks are implemented:
  • terraform_fmt -> used to rewrite Terraform configuration files to a canonical format and style. Using terraform command.
  • terraform_validate -> validates the configuration files in a directory, referring only to the configuration and not accessing any remote services such as remote state, provider APIs, etc. Using terraform command.
  • terraform_docs -> generate documentation from Terraform code using terraform-docs
  • terraform_tflint -> code linting using tflint
  • end-of-file-fixer -> makes sure files end in a newline and only a newline.
  • trailing-whitespace -> trims trailing whitespace.
  • check-merge-conflict -> checks for files that contain merge conflict strings
• .terraform-docs.yaml -> configuration file for terraform_docs
• .tflint.hcl -> configuration file for tflint
• .terraform-version -> file specifying terraform version which will be used by tfenv

Requirement

To use configs which are attached here, you require the following tools installed on your environment:

• tfenv
• tflint
• terraform_docs
• git
• pre-commit
• native support or plugin in your favourite IDE supporting Editorconfig

The most straightforward installation on Mac OS is:

brew install git pre-commit tflint tfenv terraform-docs

pre-commit

pre-commit hooks run before any git commit is done into the repository. To run pre-commit without committing, just run:

$ pre-commit run -a
Terraform fmt............................................................Passed
Terraform validate.......................................................Passed
Terraform docs...........................................................Passed
Terraform validate with tflint...........................................Passed
Fix End of Files.........................................................Passed
Trim Trailing Whitespace.................................................Passed
Check for merge conflicts................................................Passed

pre-commit is checking all hooks. In the case of terraform_fmt and terraform_docs, hooks also fix all issues (the overall result fails, but after rerunning, it should pass).

If you want to commit without triggering hooks, you can make it using option --no-verify:

git commit --no-verify
